UNITED STATES PATENT QFHCE Claims. (c1.12s 2c5) The primary object of the invention is to provide a globular breathing chamber or mask wherein the required medicines may be generated in a nebulous form for inhaling by persons to be treated having a drainage for collecting and dis-: charging therefrom the spent and unused liquids that accumulate therein.

Another equally important object of the invention is to provide a handle for supporting a globular breathing chamber having an atomizer or other nebulous generator mounted therein whereby a person may carry the nebulizer from place to place for individual use or may mount the same upon a support for family use or many individuals.

And still another object of the invention is to provide a nebulizer of a knock-down construction whereby the several parts thereof may be easily and readily assembled or taken apart in the. event any part thereof should become worn or. broken and yet provide a connection between each of the several parts thereof which will eliminate corrosion, oxidation or leakage as would be detrimental to the successful and safe use of the nebulizer.

Other objects of the invention will be in part obvious and in part pointed out as the description continues.

In the accompanying drawings:

Fig. 1 is a front elevation of the nebulous nebulizer with a portion of the air bulb broken away embodying one form of the present invention.

Fig. 2 is a vertical cross sectional view of the same illustrating diagrammatically in dotted lines how the medicated liquids may be supplied to the receptacle thereof, taken on the line 22 of Fig. 1.

Fig 3 is a horizontal section taken on the line 33 of Fig. 2 in the direction of the arrow points.

Fig. 4 is another horizontal section taken on the line 4-4 of Fig. 2 in the direction of the arrow points.

Fig. 5 is a side elevation of the metallic retainer for the receptacle containing the required medicines.

Fig. 6 is a detail vertical sectional view of the receptacle and siphon tube and,

Fig. 7 is a sectional view of a slightly modified form of the invention.

In these drawings the numeral l indicates a 2 conventional air-bulb preferably formed fro rubber having a valve controlled air intake 2 at one end thereof so that when the bulb is compressed from its normal expanded position atmospheric air will be drawn therein and discharged therefrom through the opening within the elongated neck 3 formed with the opposite endof the bulb.

The receptacle for storing the medicines employed is preferably formed from glass in the shape of an elongated cylindrical tube 4 having a liquid holding chamber therein. The air inlet end 5 of this tube is provided with a bulged portion so that when. the inlet end 5 is inserted within the neck 3 of the bulb, as best shown in Fig. 2 of the drawings, the bulb will be attached to the receptacle. An air tube 6 is preferably integrally and axially aligned with the inlet end 5 of the receptacle so as to communicate with the air-bulb and the upper end of this air tube 6 is provided with a nozzle 7. A siphon tube 8 parallel with and supported by the air tube 6 has it lower end terminating short of the bottom of the chamber of the receptacle and immerged in the liquids contained therein whereas the upper or discharge end of this siphon tube 8 projects over and slightly about the nozzle 1 of the air tube. Formed with the upper end of the receptacle is a vapor discharge extension or tube 9. The medicine or other liquid to be supplied to the chamber of the receptacle may be gathered within a conventional dropper ill and delivered to the chamber through the tube 9 in the manner as is illustrated in Fig. 2 of the drawings. When the receptacle is so filled with the required liquids and the air-bulb operated, atomization of the liquid will be effected whereby a vaporized medicated mist will be discharged from the tube 9.

To provide a support for this vaporizer I provide a hollow handle li preferably formed from hard rubber with a closed lower end [2 having an opening therein for receiving the neck 3 of the air-bulb. When this neck 3 is inserted within the handle H the closed lower end thereof-Will so engage about the bulged portion thereof as to firmly connect the :air-bulb thereto and form an air seal about the extension 5 of the receptacle]. A threaded metallic shell 13 engages threads formed with the inner wall of the handle H and the cylindrical receptacle 4 is inserted through the shell [3. A rubber ring or washer I4 is provided whereby the receptacle is supported in a vertical direction between the upper end of the shell and the washer I4.

A breathing mask I5 is also connected to the handle H and may be supported thereby in the manner as is best shown in Figs. 1 and 2 of the drawings. This breathing mask is preferably formed from glass providing an enlarged globe having a substantially triangular shaped opening l6 formed in one of its side walls whereby the nose and mouth of the user may be inserted therethrough for receiving the benefits of the medicated vapors generated therein. An inwardly projecting flange l1 extends about this opening 16 and the rounded corners resulting from forming the same provide a protection against injury to the person using the same as well as eifecting a perfect seal between the face of the user and the glass globe. The lower portion of the globe is so formed as to provide the annular channel-way [8 whereby drippings from the inner walls of the globe may accumulate therein and a plug controlled opening 19 is provided whereby drainage may be effected from the globe and its channel-way I8.

Formed with the globe and extending contiguous with the inner edge of the channel-way 18 thereof is an enlarged tubular section 20 in which projects the discharge end 9 of the atomizer. Formed with this tubular section 20 is a reduced cylindrical section 2| and the lower end of the latter terminates in a bead 22. This cylindrical section 2| of the globe is inserted within the upper opened end of the handle II and the flexible walls of the latter extend over the bead 22. A ring 23 of the hard rubber extends over the handle H so as to force the Walls of the latter about the cylindrical portion 2| of the globe whereby the latter will be secured to the handle and yet by moving the ring 23 below the bead 22 the globe may be readily removed from the handle and access gained to the atomizer supported within the handle.

The nebulizer as shown in the preferred form of invention is portable so that it may be carried by a person and used when required, whereas in Fig. 7 I have illustrated the nebulizer as that may be termed as the family size or permanent nebulizer for home use. A suitable stand 24 is provided and the legs thereof support an annular ring 25 having its upper face so shaped as to receive the depression within the globe formed between the annular channel-way l8 and the tubular section 20 thereof. The globe may be supported upon this annular ring 25 and the atomizer and air-bulb suspended between the legs of the stand 24. Instead of having a triangular shaped opening within a side wall of the globe I provided an opening 26 in the top thereof whereby repeated use and benefits from the medicated vapors within the globe l may be enjoyed by all members of a family or any number of persons.

It is also desirable that a removable tray 21 be placed within the globe in the manner as is illustrated in dotted lines in Fig. 7 of the drawings in order to collect drainage from the nose and mouth of each user and prevent the same from being inhaled by succeeding persons. This tray has a tube 28 leading therefrom to a storage receptacle 29. A handle 30 is provided for removing the tray from the globe whereby the contents of the receptacle 29 may be emptied and cleaned.

I claim:

1. A nebulizer comprising a hollow handle formed from flexible materials, an atomizer suspended within said handle, an air-bulb connected to said atomizer and extending beyond said handle, a sealed connection caused by said handle between said atomizer and air-bulb, a globular breathing mask, a cylindrical stem projecting from said globular mask and extending within said handle and means for connecting said stem to said handle.

2.

4. A nebulizer comprising in combination a breathing mask, a cylindrical stem extending therefrom, a handle detachably secured to said stem, a screw shell in threaded connection with said handle, a receptacle supported within said screw shell and an atomizer secured to and arranged within said receptacle.
